Question

我已经在spyder中使用破折号开发了一个简单的程序，但是它显示了以下错误。

import dash
import dash_core_components as dcc
import dash_html_components as html
app = dash.Dash()
app.layout = html.Div(
        html.H1(children='Hello Dash')
)
if __name__ == '__main__':
    app.run_server(debug=True)

但是它显示了以下错误。

Traceback (most recent call last):

  File "<ipython-input-13-3c5b23764cd8>", line 5, in <module>
